Principle of work of the present utility model: sewage enters after pre-treatment sled block carries out preliminary pre-treatment and enters multi-stage biochemical sled block, exclusive efficient degreasing microbial inoculum has been added in biochemical sled block, oil in water emulsion in sewage and dissolving oil, on biologic packing material, divide and take off by microorganic adhesion.After enter sedimentation sled block, be separated by remaining suspended solids in sewage in inclined plate sedimentation pond, clear water after treatment enters water collecting basin and enters recycle system by water outlet pipeline.Blower fan in Ventilator Room sled block prizes oxygen needed for microbial decomposition organic matter in block to pre-treatment sled block, multi-stage biochemical endlessly by aerator.
The utility model, with pre-processing module, can realize the preliminary treatment of sewage, prevents the impact to biochemical module.The utility model is made up of several standalone module, can install according to on-the-spot place situation independent assortment.
The beneficial effects of the utility model are: system is when intaking oil-containing 200mg/L ~ 500mg/L, and outlet oil-containing is down to below 3mg/L.Suspended solids content is down to below 5mg/L by 50mg/L ~ 100mg/L, meets this place, station block injection water quality requirement.Water injection pressure is down to 30MPa by 31.8MPa.
The utility model is mainly used in the block that oilfield reserve is little, disperse the feature such as scattered, not only can reduce the investment of the type block water treatment surface construction, also can improve its water treatment efficiency.Meet its injection water quality index, make its extraction sewage obtain effective re-injection, increase development benefit.Have broad application prospects.
As improvement of the present utility model, otherly between the feed-water end prizing block in described back with water inlet line and pre-treatment connect cooling tower.Sewage enters cooling tower through cooling by back with water inlet line, and adjustable water temperature meets the demand of microorganism to temperature, and then after entering pre-treatment sled block carrying out preliminary pre-treatment.
As further improvement of the utility model, multi-stage biochemical sled block comprises one-level biochemistry sled block and secondary biochemical sled block, and the feed-water end that block is prized by pipeline and secondary biochemical in the water side of one-level biochemistry sled block is connected.
For the ease of cleaning or maintenance one-level biochemistry sled block, the water side of pre-treatment sled block is connected with the feed-water end that secondary biochemical prizes block by the first by-pass line.
For the ease of cleaning or maintenance secondary biochemical sled block, the water side of pre-treatment sled block is connected with the feed-water end that block is prized in sedimentation by the second by-pass line.
Because oilfield sewage has corrodibility, therefore at the inwall of pre-treatment sled block, one-level biochemistry sled block, secondary biochemical sled block, sedimentation sled block, all preservative coat is set.
For ensureing that winter, microorganism can work under the optimal temperature of 20 DEG C ~ 30 DEG C, at the outer wall of pre-treatment sled block, one-level biochemistry sled block, secondary biochemical sled block, sedimentation sled block, all insulating interlayer is set.
